Borussia Dortmund have confirmed the signing of centre-back Joane Gadou from Red Bull Salzburg. The 19-year-old has put pen to paper on a long-term contract running until 2031, with reports putting the fee at around €20m including add-ons, in line with the roughly €19.5m base figure recorded by FotMob.
The move comes just days after Niklas Süle announced his retirement from professional football at the end of the season, leaving Dortmund short at centre-back. Sporting director Ole Book described Gadou as "a modern and physically strong centre-back" who is "good in build-up play, extremely fast and also still able to develop," while CEO Lars Ricken said the club had been tracking him since his time at Paris Saint-Germain and expects him to "take on an important role with us from the start of the new season."
Salzburg lose a defender who quickly established himself as a first-team regular after joining from PSG's academy in September 2024. Gadou played every minute of the club's last 14 league games as they finished as Austrian Bundesliga runners-up in 2024/25, and made 33 appearances across all competitions in 2025/26, including Champions League play-off and Club World Cup football. It is a familiar pattern for Salzburg, who have built a business model on developing young talent and selling on for a profit — Erling Haaland and Karim Adeyemi both left for Dortmund via the same route.
Standing at 1.95m, Gadou is known for his physical presence, aerial strength and recovery pace, and has spoken of modelling parts of his game on Bayern Munich's Dayot Upamecano. He captained France at the 2024 European Under-17 Championships and has continued to represent his country at youth level, with his leadership as much a factor in Dortmund's interest as his defending. He never made a competitive first-team appearance for PSG despite being included in matchday squads, before his move to Austria accelerated his development.
At Dortmund, Gadou is expected to compete for a starting centre-back role immediately rather than serve an apprenticeship, given Süle's departure leaves a clear opening in Niko Kovač's back line. His comfort carrying the ball out from defence fits a Dortmund side that likes to build attacks through their centre-backs, and his age means the club see him as a long-term solution rather than a stop-gap.
It is the first major arrival of the summer for Dortmund and the opening signing under new sporting director Ole Book, who has spoken of refocusing recruitment on promising young players. For a club that has profited from developing raw talent before, in players like Haaland and Adeyemi, taking another gamble on a teenager from the Salzburg pipeline fits a well-worn pattern — only this time he is joining the back line rather than the front.
